Limits or divides current/voltage in a circuit
Stores/releases energy; filters, couples, and decouples signals. The #1 failure component in ECMs.
Allows current flow in one direction; rectifies, protects, clamps
Current-controlled switch/amplifier with three terminals: Base, Collector, Emitter
Voltage-controlled switch; high current with low on-resistance. The #2 failure component in ECMs.
Stores energy in a magnetic field; filters, chokes, and transforms voltage
Converts unstable input voltage to stable output voltage for ICs and circuits
Complex chips containing thousands to billions of transistors for specific functions
Provides precise clock signal for MCU timing and CAN bus synchronization
Sacrificial overcurrent protection — blows to protect expensive components downstream
Mechanical interfaces — connectors link ECU to vehicle harness, relays switch high-current loads
